Laird Unveils Cascade TEAs For Wireless Products
Laird Technologies has released its enhanced Cascade Series Thermoelectric Assemblies (TEAs) for advanced electronics and wireless products. The Cascade Series TEAs are custom-designed cooling assemblies that use multistage Thermoelectric Modules (TEMs) to achieve a high-temperature differential from ambient and are said to produce up to a 40 per cent higher cooling capacity at cold temperatures than similar offerings. The TEAs have a compact size, solid-state construction and can be located directly onto the actual device requiring cooling.
Direct placement of the TEA reduces the need in many low-temperature applications to use a conventional compressor-based cooling system. Two standard configurations, as well as custom configurations that require a minimum order quantity, are available. The standard configurations include: Air-Air (AA) - convection cooling method where heat is absorbed and dissipated by high-density heat exchangers equipped with air-ducted shrouds and fans, with products in this series including the AAC-050-24-22-00-00; and Direct-Air (DA) - conduction cooling method where heat is absorbed through a cold plate and dissipated by high-density heat exchangers equipped with air-ducted shrouds and fans, with products in this series including the DAC-035-12-02-00-00 and DAC-060-24-02-00-00.
The Cascade Series TEAs are ideal for use in analytical instruments requiring cooling to well below 0C. They are also applied in medical applications so that the temperature of samples placed in storage compartments or centrifuges can be tightly controlled. Imaging applications utilise the TEAs to cool sensitive devices to below freezing, in order to maximise the bandwidth of the light spectrum captured by the charge-coupled device. The Cascade Series TEAs adhere to tight geometric space constraints by offering high performance and reliability, and low cost of ownership. Their capabilities are enhanced by new material technologies, thinner profiles and automated assembly.
